Surgical intervention in patients with necrotizing pancreatitis

Background: This study evaluated the various surgical strategies for treatment of (suspected) infected necrotizing pancreatitis (INP) and patient referrals for this condition in the Netherlands. Methods: This retrospective study included all 106 consecutive patients who had surgical treatment for INP in the period 2000-2003 in one of eight Dutch university medical centres including three teaching hospitals. Surgical approaches included an open abdomen strategy, laparotomy with continuous postoperative lavage, minimally invasive procedures or laparotomy with primary abdominal closure. The National Hospital Registration System was searched to identify patients with acute pancreatitis who were admitted to the 90 Dutch hospitals that did not participate in the present study. Results: The overall mortality rate was 34.0 per cent, 70 per cent (16 of 23) for the open abdomen strategy, 2 5 per cent (13 of 53) for continuous peritoneal lavage, 11 per cent (two of 18) for minimally invasive procedures and 42 per cent (five of 12) for primary abdominal closure (P<0.001). During the study interval, 44 (12.2 per cent) of 362 patients with acute pancreatitis who were likely to require surgical intervention had been referred to university medical centres. Conclusion: Laparotomy with continuous postoperative lavage is the surgical strategy most often used in the Netherlands. The results of the open abdomen strategy are poor whereas a minimally invasive approach seems promising.
